The Lowdown

Alright, let’s get into it. The window kicks off with some solid, consistent groundswell rolling into Lakey Pipe. We’re looking at a stretch of days here that’ll get the stoke levels up, especially for anyone who’s comfortable in the overhead range.

The first real action hits on Thursday the 13th of August. The water’s sitting at a balmy 80°, which is pretty much bang on average for this time of year, so nothing weird going on there. Early morning sees a 7ft SSW groundswell, long period of 17 seconds, pushing through with a cross-off ESE breeze. That’s clean stuff. The combined energy is pumping at 2122, so there’s plenty of grunt in the water. Keep in mind, with a period that long (over 15 seconds), this is a true groundswell. At a reef setup like Lakey Pipe, that’s a beautiful thing – long, lined-up walls. But it does mean a bit longer between sets, so pick your moments. The afternoon cleans up even more with a glassy cross-off.

Friday the 14th keeps the goodness coming. Slightly smaller at 6ft in the morning, same SSW direction, but the period remains a lofty 16 seconds. Lighter winds, too. It’s clean and punchy. The energy is still strong at 1949. Same story Saturday the 15th: 6ft to 7ft, 17-second periods, light cross-off winds. That Saturday afternoon session is a standout, with energy hitting 2389. This is the kind of weekend where you don’t want to be anywhere else.

Sunday the 16th is another clean one, though the swell dips just a touch to 6ft to 7ft. Still solid, still clean.

Now, Monday the 17th sees a bit of a drop. Swell backs off to 5ft to 5ft, and the period shortens to 14 seconds. It’s still rideable, and the wind stays friendly, but the pulse has eased.

Tuesday the 18th looks a little funky. The morning is smaller at 4ft, but then the afternoon jumps back up to 6ft SW groundswell, 16 seconds, with energy at 2388. That afternoon session could be a sneaky good one.

Here’s where it gets interesting. Wednesday the 19th of August is the real standout of this whole run. We’ve got a 8ft to 8ft SSW to SW groundswell, with a period of 18 to 19 seconds. The energy readings are massive – 3790 in the morning and 4130 in the afternoon. That’s serious power. Winds are light cross-off, so the surface will be clean. However, at 8ft with that kind of period, this is getting into expert territory. It’s not for the faint-hearted or beginners. For the crew that can handle it, this is prime.

Thursday the 20th, the swell continues to build. Morning is 10ft SW, 16 seconds, with energy at 4334. That’s a lot of water moving. The forecast even flags that it’s too big for the break at that size. The afternoon settles back to 8ft, which is still solid. This day is for the experienced crew only.

From Friday the 21st through the weekend of the 22nd and 23rd of August, the swell holds in the 6ft to 8ft range, dropping off a little by Sunday. The wind stays cross-off, keeping it clean. The best of this stretch is Saturday the 22nd afternoon, with an 8ft SW swell, 16 seconds, and energy at 3137. Another good one for the confident surfer.

The following week, from Monday the 24th to Wednesday the 26th of August, the swell pulses down. We’re looking at 3ft to 6ft, with periods shortening to 13 to 14 seconds. It’s still surfable, but the punch is gone. Wednesday the 26th afternoon shows a spike in period to 18 seconds on a 4ft swell, which could offer some clean lines at the reef but won’t have much size.

The final few days, leading up to Thursday the 27th and Friday the 28th of August, the swell builds again, hitting 7ft to 8ft on Thursday, then dropping to 5ft to 6ft by Friday. The winds remain cross-off, so conditions stay clean, but the energy has dropped back to moderate levels.

The standout in this whole 16-day window is Wednesday the 19th of August. That big, long-period SSW groundswell with light winds is the pick of the lot. If you can handle it, that’s your day.

This is Rusty, signing off.

Information about the Lakey Pipe Surf forecast

The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
